AUXILIARY LINK.

Application led December 3, 1927. Serial No. 237,473.

Our invention relates to improvements in auxiliary links, and it consists in the combinations, constructions, and arrangements hereinafter described and claimed.

An obj ect of our invention is to provide an auxiliary link that is composed of two identical parts that may be removably secured together without any fastening devices being necessary.

A further object of our invention is to provide a device of the type described which is extremely simple in construction and in which the two parts are so constructed that they will bind together more tightly as greater tension is applied.

@ther objects and advantages will appear in the following specification, and the novel features of our invention will be particularly pointed out in the appended claim.

Our invention is illustrated in the accompanying drawing forming a part of this application, in which:

Figure 1 is a side elevation of the device showing the parts operatively connected to`- gether;

Figure and y Figure 3 is a perspective view of one of the parts.

In carrying out our invention we provide two identical parts A and B that are of the shape shown in Figure 3. The part A shown in Figure 3 is U-shaped, and has legs 1 and 2 and hook-shaped ends 3 and Ll.

2 is a top plan view of the device;

The ends 3 and 4 have grooves 5 and 6 for slidably receiving the legs of the part- B.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The ends 7 in the U-shaped parts A and B, and then these parts are secured together as shown in Figures l and 2. If desired, the legs 1 and 2 of each part may be inclined outwardly to a slight extent so that the hooks 3 and 4 will frictionally engage with the legs and provide an automatic vice.

tightening means for the de- In this way the greater the strain placed upon the parts A and B, the greater the tightening effect there will be between the parts.

The hooks 3 and 4 act as guides for the parts A and B, and also act as stops for limiting the movement of the parts into engaged position.

As already stated, the

device is extremely simple in construction and since it is made up of two identical parts it may be manufactured at small expense.

Although we have shown and described one embodiment of our invention,

it is to be understood that the same is susceptible of various changes and we reserve the right to` employ such changes as may come within the scope of the appended claim. T

We claim:

An auxiliary link each part being cal parts, having hookcomprising two identi- U-shaped and shaped ends for slidably receiving the legs of the other part, the legs of one of said parts ly so that a being inclined outwardpull upon the link when assembled will cause said parts to tighten the ends of the two members normally beingr spaced apart.
